miracle grow in begonia bulbs
Can I use Miracle Grow in begonia bulbs that are just showing small green growth? They were planted five days ago.
If the begonia corms (that's what they're called rather than bulbs,) were planted in fresh soil, you can hold off fertilizing for 2 or 3 months, then go ahead and use dilute fertilizer -- 1/4 strength package directions. If the soil was not fresh, you can use dilute fertilizer now. Fertilize once a month to every week, depending on the amount of light (more light, more fertilizer.)
